WP plugin is executed multiple times, why?

Question

API

Hello, we are making a plugin for personal use, at the moment it looks like this:

The code

<?php
/*
Plugin Name: Test
Plugin URI: https://test.ru
Description: Уведомления о новых записях
Version: 0.0.2
Author: Test
Author URI: https://test.ru
*/

const VERSION = '0.0.2';
include "/home/client/vendor/autoload.php";
use Telegram\Bot\Api;

add_action( 'publish_post', 'test_my_update');
add_action ('admin_menu','test_renderMenu');
add_action( 'admin_notices', 'test_showError');





function test_my_update( $post_id) {
    // If this is a revision, don't send the email.
    if ( wp_is_post_revision( $post_id ) ) {
        return;
    }
    $post = get_post( $post_id );

    if ($post->post_type != "post") {
        return;
    } else {

        $post_title = $post->post_title;
        $post_content = $post->post_excerpt;
        $post_uri = $post->guid;

        $telegram = new Api(get_option ("test_telegram_token"));
        $telegram->sendMessage ([
            "chat_id" => get_option ("test_telegram_id"),
            "text" => "На сайте что-то новенькое: {$post_title}\nПодробнее по ссылке:\n{$post_uri}",
            "parse_mode" => "HTML"
        ]);
    }
}

function test_renderMenu(){
    add_options_page ('Уведомления о новых записях','Уведомления о новых записях',8,'notify','test_notifyRender');
}

function test_notifyRender(){
    echo '<h1>Уведомления о новых записях</h1>';
    add_option ('test_telegram_token','None');
    add_option ('test_telegram_id','None');
    add_option ('test_vk_token','None');

    echo '<h2>Изменение настроек</h2>';

    test_renderSettings();

    test_renderFooter();
}

function test_renderFooter() {
    echo "
        <p>Данная версия плагина все еще в разработке!</p>
        <p>Текущая версия: ".VERSION."</p>
        <p><a href='mailto:[email protected]?subject=Плагин версии ".VERSION."'>Написать письмо</a></p>
    ";
}

function test_renderSettings() {
    if (isset($_POST['test_opt_btn'])) {
        if (function_exists ("current_user_can") && !current_user_can ("manage_options")) {
            die(_e ("Ooops...","test"));
        }
        if (function_exists ("check_admin_referer")) {
            check_admin_referer ("test_notify_settings_form");
        }

        $telegram_token = $_POST['test_telegram_token'];
        $telegram_id = $_POST['test_telegram_id'];

        update_option ("test_telegram_token",$telegram_token);
        update_option ("test_telegram_id",$telegram_id);
    }


    $url = $_SERVER['PHP_SELF'].'?page=notify&amp;updated=true';
    echo '<p>Уведомления в Telegram</p>';
    echo "<form name='test_notify_settings' method='post' action='{$url}'>";

    if (function_exists ('wp_nonce_field')) {
        wp_nonce_field ('test_notify_settings_form');
    }
    echo "
    <p>
        <label for='test_telegram_token'>Токен Telegram</label><br>
    <input type='text' id='test_telegram_token' name='test_telegram_token' placeholder='Токен Telegram' value='".get_option ("test_telegram_token")."'>
    </p>
    <p>
        <label for='test_telegram_id'>id Канала, беседы куда слать уведомления</label><br>
    <input type='text' id='test_telegram_id' name='test_telegram_id' placeholder='id беседы Telegram' value='".get_option ("test_telegram_id")."'>
    </p>
    <p>
        <input type='submit' value='Сохранить' name='test_opt_btn'>
    </p>
    ";
    echo '<form>';
}

function test_showError() {
    if (get_option ("test_telegram_id") == null or get_option ("test_telegram_token") == null) {
        echo "<div class='error notice'><p>Вы не указали необходимые настройки для уведомлений, пожалуйста перейдите <a href='/wp-admin/options-general.php?page=notify'>сюда</a> для настройки.</p></div>";
    }
}

The problem is that when a new entry is published, the notification is sent twice instead of once.
I sit for 2 hours, I can not understand why, can someone tell me?
I catch the event about the publication of a new record like this: Thanks in advance!
add_action( 'publish_post', 'test_my_update');
